How to crush the gallstones

Hi there

I am having a bunch of 1/2 inch calcified Gallstones which can be seen through Ultra-sound. I am preparing myself for Liver Flush however affraid of stones got stuck in the ducts so I think I need to break them into smaller pieces before flush. Please tell me the best recipe to crush the stones. Should I use Gold Coin Grass only or a combination of Gold Coin Grass, Malic Acid and Apple juice? Where can I find the Gold Coin Grass and Malic Acid? Thanks for your help. Julia.
